Inverter Duty Motors

The need for proper motor grounding is extremely important in preventing premature bearing failure, which could result in high maintenance costs or worse - facility downtime. While there are several techniques and practices to ground the motor, the most common and economical is a shaft grounding device mounted to the frame of the motor. ABB’s Baldor-Reliance® inverter duty motors use one of three common types of shaft grounding devices: shaft-grounding brushes, bearing protection rings and grounding bearing isolators.
